Doug and I were talking about stargate over lunch, and I realized that I don't know anything about wormholes. But then I bombed my brain with:

(setq q '(list processing hurts my brain))
(list (cadddr q) (car(reverse q)) (caddr q))

space will eat your mind, or at least several hours of your life. And then some wormholes will camp out and declare time to irrelevant and you really need to start reading more about them. But, they'll tell you that probably need some background reading first.
